About The Position

PBC Linear, a recognized leader in linear motion innovation, is seeking a highly skilled Sr Mechanical Design Engineer to join our Product Engineering team. For over 40 years, PBC Linear has pioneered the industry, establishing leadership through developments like the self-lubricating plain linear bearing. We are a major US manufacturer committed to engineering excellence and supplying precision components, guides, rails, and advanced actuators.

This is a critical, hands-on engineering role focused on driving innovation within the linear motion industry. If you thrive on tackling complex engineering challenges, owning projects from concept to completion, and pushing the boundaries of mechanical design, we want to hear from you.

Requirements

• Bachelor’s Degree in Mechanical Engineering or a related field.
• Familiarity with motion control systems (drives, motors, encoders, sensors) and electro-mechanical systems.
• Experience with component testing, rapid prototyping, and reverse engineering.
• Knowledge of various manufacturing processes, including extrusion, machining, injection molding, and assembly.

Nice To Haves

• 5+ years of direct, proven experience in the linear motion industry (including bearings, guides, actuators, or motion systems).
• Proven experience designing linear motion products, such as recirculating or plain bearing technology, lead screw or ball screw actuators, or profile rail systems.
• Experience Developing products and managing projects within a gated product development system.
• Experience creating catalog content, product datasheets, and working with web-based product configurators.

Responsibilities

• Lead clean-sheet mechanical designs for linear bearings, actuators, and motion systems.
• Own the full-cycle development process, ensuring designs move efficiently from concept through validation and ultimate release.
• Identify design differentiators by reverse engineering competitive products.
• Perform essential engineering calculations, including load analysis, stress analysis, drive load analysis, motion profile analysis, tolerance stack up analysis, and material selection.
• Develop comprehensive test plans and execute validation testing to prove models and iterate designs accordingly.
• Utilize CAD (SOLIDWORKS) and FEA tools for modeling and simulation.
• Create and maintain accurate 3D models, 2D drawings, and Bills of Materials (BOMs).
• Ensure designs align with customer needs and manufacturability by working closely with sourcing, manufacturing, and marketing teams.
• Support product launches by providing necessary CAD assets, technical data, and content for catalogs.
